Another advantage that nobody has mentioned so far is the fact that if you're doing something time-consuming (
noding, playing
Counter-Strike or whatnot), hand-rolled cigarettes are perfect. Because they're not
doctored with all kinds to make them burn better and be more
aesthetically pleasing, you can actually lay your rolled cigarette in the
ashtray and carry on with what you're doing, and it will
extinguish itself, ready to be re-lit when you have the time to finish it.
Compare this to regular
cigarettes, which will leave an
impressive (but ultimately
useless) line of ash down to the
filter.
Hand rolled cigarettes - For the smoker on the go!
